They look like they need something but flowers are probably not that something...
I'm a little confused, this looks and sounds like an outdoor grow, right? If so then you probably got them in the ground barely in time depending on where you are at, but you might be a little late, if I remember correctly the best time to plant is (Mar-Jun).
There are a few other things I'm surprised haven't been commented on, like if it is outdoors how are you going to 'start flowering or let em grow more'? I might be wrong but you might have a difficult time controlling this as mother nature kinda has her own light schedules, now you could supplement to compensate for a schedule that moms isn't on... Look, at this point maybe you should dig em up and bring them inside? Also what is that residue all over the ground? It looks like mold, fungus or something that should not be there, in the first pic it looked like sand but in the other it didn't look like sand maybe clay?
